Abstract
Objective: In this study, we aimed to compare the short-term safety of two digestive tract reconstruction techniques, laparoscopic total abdominal overlap anastomosis and laparoscopic-assisted end-to-side anastomosis, following radical resection of Siewert Type II adenocarcinoma of the esophagogastric junction. Methods: In this retrospective cohort study, we analyzed relevant clinical data of 139 patients who had undergone radical surgery for Siewert Type II esophagogastric junction adenocarcinoma. These included 89 patients treated at the First Affiliated Hospital of Air Force Medical University from November 2021 to July 2023, 36 patients treated at the First Affiliated Hospital of Xi'an Jiaotong University from December 2020 to June 2021, and 14 patients treated at the Yuncheng Central Hospital in Shanxi Province from September 2021 to November 2022. The group consisted of 107 men (77.0%) and 32 women (23.0%) of mean age 62.5±9.3 years. Forty-eight patients underwent laparoscopic total abdominal overlap anastomosis (overlap group), and 91 laparoscopic-assisted end-to-side anastomosis (end-to-side group). Clinical data, surgical information, pathological findings, postoperative recovery, and related complications were compared between the two groups. Results: There were no significant differences in general clinical data between the overlap and end-to-side anastomosis groups (all P>0.05), indicating comparability. There was no significant difference in operation time (267.2±60.1 minutes vs. 262.8±70.6 minutes, t=0.370, P=0.712). However, the intraoperative blood loss in the overlap group (100 [50, 100] mL) was significantly lower compared to the end-to-side group (100[50, 175] mL, Z=2.776, P=0.005). Compared to the end-to-side group, longer distances between the tumor and distal resection margin proximal(1.7±1.0 cm vs. 1.3±0.9 cm, t=2.487, P=0.014) and the tumor and distal resection margin (9.5±2.9 cm vs. 7.9±3.5 cm, t=2.667, P=0.009) were achieved in the overlap group. Compared with the end-to-side group, the overlap group achieved significantly earlier postoperative ambulation (1.0 [1.0, 2.0] days vs. 2.0 [1.0, 3.0] days, Z=3.117, P=0.002), earlier time to first drink (4.7±2.6 days vs. 6.2±3.0 days, t=2.851, P=0.005), and earlier time to first meal (6.0±2.7 days vs. 7.1±3.0 days, t=2.170, P=0.032). However, the hospitalization costs were higher in the overlap group (113, 105.5±37, 766.3) yuan vs. (97, 250.2±27, 746.9) yuan; this difference is significant (t=2.818, P=0.006). There were no significant differences between the two groups in postoperative hospital stay, total number of lymph nodes cleared, or time to first postoperative flatus (all P>0.05). The incidence of surgery-related complications was 22.9%(11/48) in the overlap group and 19.8% (18/91) in the end-to-side group; this difference is not significant (χ²=0.187, P=0.831). Further comparison of complications using the Clavien-Dindo classification also showed no significant differences (Z=0.406, P=0.685). Conclusions: Both laparoscopic total abdominal overlap anastomosis and laparoscopic-assisted end-to-side anastomosis are feasible for radical surgery for Siewert Type II esophagogastric junction adenocarcinoma. Laparoscopic total abdominal overlap anastomosis achieves longer proximal and distal resection margins and better postoperative recovery; however, end-to-side anastomosis is more cost-effective.

Abstract
Objective: To investigate the relationship between the levels of selenium, iron and copper in cord blood of neonates and the risk of congenital heart disease (CHD), and analyze their interaction effects. Methods: The subjects were obtained from the birth cohort in Lanzhou area established from 2010 to 2012. A baseline survey was conducted in the first trimester, and the follow-up was conducted in the second trimester, third trimester and 42 days after delivery. The umbilical vein blood was collected from newborns at delivery, and information on their birth outcomes was extracted from medical records. A nested case-control study was used to select 97 neonates with CHD newly diagnosed by echocardiography as the case group, and 194 neonates were selected as the control group by 1∶2 matching according to their mother's age, block and CHD onset time. Inductively coupled ion mass spectrometry was used to detect the concentrations of selenium, iron and copper in neonatal cord blood. The element exposure was categorized into three groups, the low, medium and high concentrations, according to the quartiles Q1 and Q3 of selenium, iron and copper concentrations in the control group. The association between cord blood selenium, iron and copper concentrations and CHD was analyzed by conditional logistic regression model using medium concentration as the reference standard. The association of their interactions with CHD was analyzed by a phase multiplication model. Results: The M (Q1, Q3) concentration of neonatal cord blood copper was 746.12 (467.48, 759.74) μg/L in the case group and 535.69 (425.21, 587.79) μg/L in the control group, with a statistically significant difference between the two groups (P<0.05). After adjustment for confounders, logistic regression models showed that the risk of CHD development was increased in neonates with either high copper in cord blood (OR=4.062, 95%CI: 2.013-8.199) or high copper combined with high iron (OR=3.226, 95%CI: 1.343-7.750). No correlation was observed between selenium and iron concentrations and the development of CHD in neonates. There was a multiplicative interaction between copper and iron in cord blood on the risk of developing CHD (OR=1.303, 95%CI: 1.056-1.608). Conclusion: There is a multiplicative interaction between iron and copper elements. The high copper and the high copper combined with high iron in umbilical cord blood are risk factors for neonatal CHD.

Abstract
Radical gastrectomy with D2 lymphadenectomy has been widely performed as the standard surgery for patients with gastric cancer in major medical centers in China and abroad. However, the exact extent of lymph node dissection is still controversial. In the latest version of the Japanese Gastric Cancer Treatment Guidelines, No. 14v lymph nodes (along the root of the superior mesenteric vein) are again defined as loco-regional lymph nodes, and it is clarified that distal gastric cancer presenting with infra-pyloric regional lymph node (No.6) metastasis is recommended for D2+ superior mesenteric vein (No. 14v) lymph node dissection. To explore the relevance and clinical significance of No.6 and No.14v lymphadenectomy in radical gastric cancer surgery, a review of the national and international literature revealed that No.6 lymph node metastasis was associated with No.14v lymph node metastasis, that No.6 lymph node status was a valid predictor of No.14v lymph node negative status and false negative rate, and that for gastric cancer patients with No. 14v lymph node negative and No.6 lymph node positive, the dissection of No.14v lymph node may also have some significance. The addition of No. 14v lymph node dissection in radical gastrectomy is safe, but it is more important to distinguish the patients who can benefit from it. Professor Liang Han of Tianjin Medical University Cancer Hospital is currently leading a multicenter, large-sample, prospective clinical trial (NCT02272894) in China, which is expected to provide higher level evidence for the clinical significance of lymph node dissection in No.14v.

Abstract
Objective: The investigation and research on the application status of Hepatic Venous Pressure Gradient (HVPG) is very important to understand the real situation and future development of this technology in China. Methods: This study comprehensively investigated the basic situation of HVPG technology in China, including hospital distribution, hospital level, annual number of cases, catheters used, average cost, indications and existing problems. Results: According to the survey, there were 70 hospitals in China carrying out HVPG technology in 2021, distributed in 28 provinces (autonomous regions and municipalities directly under the central Government). A total of 4 398 cases of HVPG were performed in all the surveyed hospitals in 2021, of which 2 291 cases (52.1%) were tested by HVPG alone. The average cost of HVPG detection was (5 617.2±2 079.4) yuan. 96.3% of the teams completed HVPG detection with balloon method, and most of the teams used thrombectomy balloon catheter (80.3%). Conclusion: Through this investigation, the status of domestic clinical application of HVPG has been clarified, and it has been confirmed that many domestic medical institutions have mastered this technology, but it still needs to continue to promote and popularize HVPG technology in the future.

Abstract
The incidence of adenocarcinoma of esophagogastric junction (AEG) is increasing at home and abroad. Laparoscopic surgery has gradually become the main means of surgical treatment of this kind of tumor. However, due to the special anatomical position of the tumor, the high position away from the broken esophagus and the narrow space in the mediastinum, laparoscopic anastomosis has the characteristics of difficult anastomosis and high anastomosis position. There is a high risk of anastomotic leakage after operation, which may cause serious consequences. Early identification of anastomotic leakage and unobstructed drainage by various means are the key to treatment. With the development of endoscopic technology, endoscopic methods such as covered stent and vacuum-assisted closure further improve the treatment efficacy. As a salvage measure, surgical treatment can achieve good treatment outcome, while accompanied by risk of complications and mortality, so we must strictly grasp the indications.

Abstract
Abstract Objective To retrospectively analyze the characteristics of the traumatic rupture of intracranial internal carotid artery in order to provide reference for forensic expertise examination and identification. Methods A total of 11 autopsy cases of traumatic rupture of intracranial internal carotid artery were collected. The gender, age, cause of injury, blood loss on the scene, location of internal carotid artery rupture, hardening degree of the rupture of the wall, brain injury, blood ethanol content and cause of death were also recorded. Results All 11 cases died on the scene, of which 7 died from traffic accidents, 2 falls from height and 2 from bare handed injuries. None of the 11 victims suffered serious head and body surface injury. The internal carotid artery rupture in the 9 cases of traffic injury and fall from height injury occurred in the cavernous segment. In all these cases, there were transverse fractures of the middle cranial fossa with the carotid sulcus involved, and minor intracranial hemorrhage and brain contusion. In 2 cases of bare handed injuries, internal carotid artery rupture occurred in the ophthalmic artery segment, accompanied by fatal intracranial hemorrhage and diffuse axonal injury, but no skull fracture. All 11 cases showed full-thickness rupture of the vessel wall, and the long axis of the wounds was perpendicular to those of the artery. Conclusion The incidence of intracranial internal carotid artery rupture in high-energy trauma events such as traffic accidents and high falls deserves attention. Injuries of the cavernous segment or ophthalmic segment might be more common. The main injury mechanism of intracranial internal carotid artery rupture might be that the blood vessels were pulled and the bone fragments caused damage.

Abstract
Abstract Objective To provide reference for medical and health services and forensic expertise, the causes and manners of death of psychiatric patients were analyzed retrospectively. Methods A total of 105 autopsy cases of psychiatric patients accepted and settled by Institute of Forensic Science of Criminal Investigation Police University of China from 2004 to 2019 were collected. The cases were divided into four groups: disease death, suicidal death, accidental death and homicidal death. The common causes of death of each group were statistically analyzed and the differences in age, disease duration, body mass index (BMI) and gender among the groups were assessed. Results Of the 105 cases, 60 were male and 45 were female, the course of psychosis was (12.9±10.4) years, the age of the deceased was (51.3±11.4) years, and 61.0% was schizophrenic. There were 50 cases (47.6%) in the disease death group, in which the psychiatric patients were the oldest and had the longest course of psychosis and lowest BMI. Pulmonary thromboembolism, respiratory infections, and cardiogenic disease were the most common causes of death in the group. There were 26 accidental deaths (24.8%), among which traffic accidents were the most common cause of death. There were 15 homicidal deaths (14.3%), all of which were male, with craniocerebral injury being the most common cause of death. There were 14 suicidal deaths (13.3%). In suicidal death group, the age of the deceased was the youngest, the course of psychosis was the shortest and falling from the height was the most common way to commit suicide. Conclusion Understanding the common causes of death of psychiatric patients may contribute to developing measures to reduce the mortality rate of the population. It is necessary to investigate the age, course of psychosis and gender of the deceased when assessing the manner of death.

Abstract
AIM This study aimed to analyse bacterial community and biomineralization products from Wudalianchi non-active volcanic field and the relationship between magnetization and bacterial community. METHODS AND RESULTS Eighteen sediment samples obtained from Wenbo Lake, high-throughput sequencing and quantitative PCR (qPCR) were separately employed to investigate the bacterial community composition dynamics and abundance variation of the sediment sample with the highest iron-reducing capacity during incubation. The mineralization products were characterized by transmission electron microscopy, scanning electron microscopy, X-ray diffraction (XRD), Raman spectroscopy, vibrating sample magnetometer (VSM) and variable-temperature magnetism analyses. The results showed that the highest iron reduction rate was 98·06%. Seven phyla were identified as dominant bacterial phyla during the incubation process. Iron-reducing bacteria (FeRB) including Geobacter, Desulfosporosinus and Clostridium were involved in the iron mineralization process. The 16S rDNA copy numbers of sediment decreased quickly and then stayed steady during the incubation. Bacteria with rod-shaped and spheroid species were involved in extracellular iron reduction to produce magnetic particles with massive aggregation and columnar structures on the mineral surface morphologies. The materials produced by the microbial community over the incubation period were sequentially identified as siderite, magnetite and maghemite. The magnetism of the mineral samples gradually increased from 0·31748 to 33·58423 emu g-1 with increased incubation time. The final products showed relatively stable magnetism under 0-400 K. Meanwhile, the saturation magnetization (MS ) of the mineralized substance was tightly associated with bacterial diversity (P < 0·05). CONCLUSIONS Bacterial community varied during incubation of iron-reducing sediment of volcanic lake. Various iron mineral crystals were in turn formed extracellularly by FeRB. The magnetism of mineralized products was tightly associated with bacterial community. SIGNIFICANCE AND IMPACT OF THE STUDY These results not only help us to better understand the iron mineralization of FeRB in the volcanic lake sediments but also provide basic information for the future application of FeRB in environmental bioremediation.

Abstract
Dentritic cells (DCs) dysfunction has been verified detrimental for sepsis and B and T lymphocyte attenuator (BTLA) is an immune-regulatory receptor shown to be associated with DCs dysfunction. However, the role of BTLA expression in myeloid DCs (mDCs) in neonatal sepsis is unknown. In the current study, we found BTLA-expressing mDCs were elevated in neonates with sepsis and the BTLA expression level in mDCs was positively correlated to the severity of sepsis. The presence of BTLA negatively regulated the phagocytosis capacity and bactericidal ability of mDCs as well as the maturation markers expression of mDCs. Our data also showed BTLA+mDCs shifted into an anti-inflammatory phenotype with decreased expression of IL-6, TNF-α and IL-12, but increased IL-10. in addition, we found BTLA expression indeedly altered the mDCs allo-stimulatory capacity. Therefore, BTLA expression in mDCs could be a useful predictive marker for neonatal sepsis and targeting BTLA expression in mDCs may be a new therapeutic strategy.

Abstract
The composites of NiCo2O4 with unique structures are extensively explored as promising electrodes. In this work, core-shell structured nanowires anchored on nickel foam are synthesized by the hydrothermal synthesis of NiCo2O4 as core and subsequent electrodeposition of α-Co(OH)2 as shell. The core-shell composites exhibit enhanced electrochemical performances ascribing to the synergistic reactions from both materials, showing higher specific capacitance than any single component. By changing the deposition time, the mass loading of α-Co(OH)2 can be easily controlled. The electrochemical performances of the hybrid electrodes are diverse with the mass loading of Co(OH)2. The optimized hybrid electrode with 3 mins electrodeposition exhibits the highest specific capacitance (1298 F g-1 at 1 A g-1) among all electrodes. The redox reaction is a main contributor to the total specific capacitance through electrochemical kinetics analysis. An asymmetric supercapacitor assembled by the optimized material as positive electrode and activated carbon as negative electrode can achieve a relatively high energy density of 39.7 Wh kg-1 at a power density of 387.5 W kg-1 (at 0.5 A g-1) in a voltage of 1.55 V.

Abstract
Little is known about how tuberculosis (TB) impairs dendritic cell (DC) function and anti-TB immune responses. We previously showed that the B and T lymphocyte attenuator (BTLA), an immune inhibitory receptor, is involved in TB pathogenesis. Here, we examined whether BTLA expression in TB affects phenotypic and functional aspects of DCs. Active TB patients exhibited higher expression of BTLA in myeloid dendritic cells (mDCs) and plasmacytoid DCs (pDCs) subsets compared with healthy controls (HCs). BTLA expression was similarly high in untreated TB, TB relapse, and sputum-bacillus positive TB, but anti-TB therapy reduced TB-driven increases in frequencies of BTLA+ DCs. BTLA+ DCs in active TB showed decreased expression of the DC maturation marker CD83, with an increased expression of CCR7 in mDCs. BTLA+ DCs in active TB displayed a decreased ability to express HLA-DR and to uptake foreign antigen, with a reduced expression of the co-stimulatory molecule CD80, but not CD86. Functionally, BTLA+ DCs in active TB showed a decreased production of IL-12 and IFN-α as well as a reduced ability to stimulate allogeneic T-cell proliferative responses. BTLA+ mDCs produced larger amounts of IL-4 and TGF-β than BTLA− mDCs in both HCs and APT patients. BTLA+ DCs from active TB patients showed a reduced ability to stimulate Mtb antigen-driven Th17 and Th22 polarizations as compared to those from HCs. Conversely, these BTLA+ DCs more readily promoted the differentiation of T regulatory cells (Treg) and Th2 than those from HCs. These findings suggest that TB-driven BTLA expression in DCs impairs the expression of functional DC surrogate markers and suppress the ability of DCs to induce anti-TB Th17 and Th22 response while promoting Th2 and Foxp3+ Tregs.

Abstract
Regulatory B cells (Bregs) have critical roles as a negative regulator of immunity, mainly due to the fact that it secrets high a level of interleukin 10 (IL-10). Recently, a new subset of Bregs was identified as a key source of IL-35, which is an immunosuppressive cytokine and conventionally thought to be secreted by regulatory T cells (Tregs). Our previous study showed that the level of IL-35 in serum was elevated in the patients with active tuberculosis (ATB). However, none of the studies reported that IL-35 is secreted by B cells in ATB patients. In the current study, we found that the mRNA expressions of the both subunits (p35 and Ebi3) of IL-35 by circulating B cells were increased in ATB patients. By using immunohistochemistry and immunofluorescence staining, we found a subset of B cells infiltrated into the tuberculous granuloma of ATB patients also expressed IL-35. Moreover, Mycobacterium tuberculosis (MTB) lysate stimulation assay also demonstrated higher levels of IL-35 were exerted by MTB lysate within purified B cells from healthy control group (HC). Flow cytometry analysis further showed that the IL-35-producing B cells from ATB patients produced a higher level of IL-10. Taken together, IL-35-producing B cells may play a regulatory role during MTB infection by producing IL-10.

Abstract
Objective: To investigate the safety and feasibility of laparoscopic operation in thetreatment of gastric gastrointestinal stromal tumor (GIST) at unfavorable positions. Methods: A retrospective cohort study was conducted to analyze the clinical data of patients with gastric GIST at unfavorable positions confirmed by pathology after surgery (laparoscopy or laparotomy) at the Southwest Hospital of the Army Medical University and the Minda Hospital of Hubei Minzu University from June 2008 to June 2018. The unfavorable positions of stomach are defined as the esophagogastric junction, the proximal cardia of gastric lesser curvature, the pylorus of stomach, the posterior wall of stomach and the antrum of stomach.Exclusion criteria:(1) preoperative chemotherapy or imatinib therapy; (2) diameter of tumor > 10 cm; (3) tumor metastasis or concurrence of other malignant tumors. A total of 244 patients (238 in Southwest Hospital and 6 in Minda Hospital) were enrolled, including 122 males and 122 females with age of 41-70years. Operative methods should be adopted according to patients' wishes. There were 146 cases in the laparoscopic surgery group and98 cases in the open surgery group. The intraoperative blood loss, operative time, postoperative first flatus time, postoperative firstfeeding time,average hospital stay, morbidity of postoperative complication,1-,3-,and 5-year recurrence free survival(RFS) and overall survival (OS)rate were compared between the two groups. Results: There were no significant differences in sex, age, tumor size, tumor risk grade or growth pattern between the laparoscopic and the open surgery groups (all P>0.05),and these two groups were comparable. Compared with open group, laparoscopic group had less intraoperative blood loss [(31.4±2.3) ml vs. (143.9±3.7) ml, t=292.800, P<0.001], shorter postoperative first flatus time [(2.1±0.7) days vs.(3.8±0.8) days, t=17.550,P<0.001], shorter postoperative first feeding time [(2.1±0.5) days vs.(2.3±1.7) days, t=1.339,P=0.020], shorter hospital stay [(8.6±2.6) days vs. (13.6±3.2) days, t=13.410, P<0.001], and lower morbidity of postoperative complication [16(11.0%) vs. 21(21.4%),χ2=4.996,P=0.025], whose differences were statistically significant. While the operation time was similar in two groups [(124.7±15.8) minutes vs. (120.9±14.5) minutes, t=1.903,P=0.058]. The median follow-up of all the patients was 43 (1 to 119) months.In laparoscopic group and open group, the 1-, 3- and 5-year RFS were 94.5% vs. 93.9%, 91.1% vs. 90.8%,and 82.2% vs. 81.6%, respectively, and 1-, 3- and 5-year OS were 98.6% vs. 95.9%, 95.9% vs. 94.9%,and 91.1% vs. 88.8%, respectively, whose differences were not statistically significant (all P>0.05). Conclusion: In the experienced gastrointestinal surgery center, laparoscopic resection of gastric GIST at unfavorable position is safe and feasible, achieving the same efficacy of open surgery.

Abstract
Dendritic cell (DC) plays an important role in the immune response against pulmonary tuberculosis. However, the phenotypic profile of DC subsets in peripheral blood in individuals with active pulmonary tuberculosis (APT) is still inconclusive. Here, we demonstrated that the absolute numbers of total DC (tDC), myeloid DC (mDC) and plasmacytoid DC (pDC) in individuals with APT were decreased compared to healthy controls (HCs). The decreased number of DCs, especially of pDC, seems to be a useful diagnostic marker of APT. Meanwhile, the number of DCs was associated with the prolonged/complicated TB, ATD treatment effect and lymphocyte immune reactions, as manifested that relapsed APT patients with a higher number of tDC and lower number of pDC compared to newly diagnosed patients. Interestingly, mDC from APT patients displayed high expressions of CD83 and CCR7, but pDC displayed low expressions of CD83 and CCR7. Moreover, DCs from APT patients expressed lower levels of HLA-DR and CD80, but expressed a higher level of CD86 than those from HCs. However, the antigen uptake capacity of DC subsets was not different between APT and HCs, despite the antigen uptake capacity of pDC was much lower than that of mDC in both APT patients and HCs. Our data represent a systematic profile of DC subsets in the blood of APT patients, and would represent a useful biomarker for APT.

Abstract
OBJECTIVE Tuberous sclerosis complex (TSC) is a multisystem genetic disorder caused by mutations in the TSC1 and TSC2 genes, but the molecular events contributing to TSC are not well understood. However, little is known about the role of microRNAs in TSC. To explore the microRNA differential expression profile between tuberous sclerosis complex cell line TSC2-/- MEFs and normal type cell line TSC2+/+ MEFs, and to provide new clues to study the mechanism of microRNA function in tuberous sclerosis complex. METHODS TSC2-/- MEFs and TSC2+/+ MEFs cell lines were cultured in vitro, each with three samples chosen as the experimental group and the control group respectively. Total RNA was isolated using TRizol and purified with RNeasy mini kit according to manufacturer's instructions. RNA quality and quantity were measured by using nanodrop spectrophotometer and RNA integrity was determined by gel electrophoresis. Total RNAs were extracted by TRizol, followed by RNA quantification and quality control. MicroRNA profiles were analyzed by microarray and the threshold value used to screen up-regulated more than 2-fold change or down-regulated less than 0.5-fold change compared with controls. Real-time PCR was used to validate the reliability of microarray. Cell counting kit-8 (CCK-8) assay was performed to evaluate the proliferation. RESULTS Fourteen microRNAs, including miR-18a-5p, miR-376c-3p, miR-136-5p, miR-467c-5p, miR-467b-5p, miR-5104, miR-3098-3p, miR-30a-3p, miR-302b-3p, miR-18a-3p, miR-19b-1-5p, miR-19a-5p, miR-20a-5p, miR-155-5p, were up-regulated, while twenty-six microRNAs, including miR-200b-3p, miR-450a-1-3p, miR-542-5p, miR-199b-5p, miR-10a-5p, miR-466c-5p, miR-450a-5p, miR-450b-5p, miR-542-3p, miR-351-5p, miR-322-3p, miR-199a-3p, miR-335-5p, miR-10b-5p, miR-351-3p, miR-155-3p, miR-497a-5p, miR-503-5p, miR-148a-3p, miR-1843a-5p, miR-199a-5p, miR-490-5p, miR-450a-2-3p, miR-322-5p, miR-214-3p, miR-450b-3p, were down-regulated in tuberous sclerosis complex cell line TSC2-/- MEFs compared with normal type cell line TSC2+/+ MEFs (P<0.05). Real-time PCR confirmed the expressions of miR-136-5p, miR-30a-3p, miR-302b-3p, miR-10b-5p, miR-148a-3p, miR-199a-5p consistent with the microarray data (P<0.05). Furthermore, the overexpression of miR-199a-5p significantly inhibited cell proliferation (P<0.05). CONCLUSION There are differences in the expression of miRNA between the tuberous sclerosis complex cell line TSC2-/- MEFs and normal cell line TSC2+/+ MEFs. MiRNA-199a-5p plays an important role in tuberous sclerosis complex, which may be developed as an important molecular target for the treatment of tuberous sclerosis complex.

Abstract
Despite past extensive studies on B and T lymphocyte attenuator (BTLA)-mediated negative regulation of T cell activation, the role of BTLA in antigen presenting cells (APCs) in patients with active pulmonary tuberculosis (ATB) remains poorly understood. Here, we demonstrate that BTLA expression on CD11c APCs increased in patients with ATB. Particularly, BTLA expression in CD11c APCs was likely associated with the attenuated stimulatory capacity on T cells (especially CD8+ T cell) proliferation. BTLA-expressing CD11c APCs showed lower antigen uptake capacity, lower CD86 expression, higher HLA-DR expression, and enhanced IL-6 secretion, compared to counterpart BTLA negative CD11c APCs in healthy controls (HC). Interestingly, BTLA-expressing CD11c APCs from ATB patients displayed lower expression of HLA-DR and less IL-6 secretion, but higher expression of CD86 than those from HC volunteers. Mixed lymphocyte reaction suggests that BTLA expression is likely associated with positive rather than conventional negative regulation of CD11c APCs stimulatory capacity. This role is impaired in ATB patients manifested by low expression of HLA-DR and low production of IL-6. This previous unappreciated role for BTLA may have implications in the prevention and treatment of patients with ATB.

Abstract
Roles of human IL-37 in infections remain poorly characterized. Although plasma IL-37 is elevated in patients with tuberculosis (TB), IL-37 source and immune correlate in TB have not been investigated. It is also unknown whether and how TB can influence the ability of immune cells to mount innate responses of IL-37 and pre-inflammatory cytokines. Here, we demonstrated that IL-37b-producing monocytes coincided with a source of elevated plasma IL-37b in TB patients. While IL-37b production in TB was associated with prolonged/complicated TB, TB burdens and inflammatory reactions, it negatively correlated with immune responses of pro-inflammatory cytokines IL-1β, IL-6 and TNF-α or IL-10. Interestingly, mycobacterial re-infection of monocytes from TB patients, but not healthy BCG-vaccinated controls, enhanced or sustained IL-37b production by cultured monocytes. TB-sensitized monocytes from TB patients mounted more robust immune responses of IL-37b than those of pre-inflammatory cytokines during mycobacterial re-infection in culture. Our data represent new findings in terms of IL-37b responses, immune correlates and potential mechanisms in TB patients.

Abstract
Despite the recent appreciation of interleukin 35 (IL-35) function in inflammatory diseases, little is known for IL-35 response in patients with active tuberculosis (ATB). In the current study, we demonstrated that ATB patients exhibited increases in serum IL-35 and in mRNA expression of both subunits of IL-35 (p35 and EBI3) in white blood cells and peripheral blood mononuclear cells. Consistently, anti-TB drug treatment led to reduction in serum IL-35 level and p35 or EBI3 expression. TB infection was associated with expression of p35 or EBI3 protein in CD4(+) but not CD8(+) T cells. Most p35(+)CD4(+) T cells and EBI3(+)CD4(+) T cells expressed Treg-associated marker CD25. Our findings may be important in understanding immune pathogenesis of TB. IL-35 in the blood may potentially serve as a biomarker for immune status and prognosis in TB.

Abstract
Ulcerative colitis (UC) is an inflammatory bowel disease, and its pathogenesis involves a variety of genetic, environmental, and immunological factors such as T helper cells and their secreted cytokines. B and T lymphocyte attenuator (BTLA) is an immunoregulatory receptor that has a strong suppressive effect on T-cell function. However the role of BTLA in UC remains poorly understood. Here we demonstrated that the frequency of BTLA-expressing CD3(+) T cells, especially CD4(+) T cells, increased in blood and mucosa in mice with DSS-induced colitis. The frequency of Foxp3-expressing cells in BTLA+ CD4(+) T cell from lamina propria mononuclear cells (LPMCs) was much higher in DSS-treated mice than that in controls. Similarly, the proportion of IL-17+ cells in BTLA+ CD4(+) T cells from LPMCs in DSS-treated mice is much higher than that in controls, while no perceptible difference for the proportion of IFN-γ+ cells in BTLA+ CD4(+) T cells was noted between DSS-treated mice and controls. Treatment of mesalazine, an anti-ulcerative colitis drug, down-regulated Foxp3 and IL-17 expression in BTLA positive T cells along with attenuated severity for colitis. Our findings indicate that BTLA may be involved in the control of inflammatory responses through increasing Foxp3 expression, rather than attenuating IL-17 production, in DSS-induced colitis.

Abstract
Despite past extensive studies, the role of B and T lymphocyte attenuator (BTLA) in αβ T cells in patients with active pulmonary tuberculosis (ATB) remains poorly understood. Here we demonstrate that BTLA expression on αβ T cells is decreased in patients with M. tuberculosis (Mtb) infection. Particularly, BTLA expression levels are likely critical for αβ T cells to manifest and maintain an active central memory phenotype with high capacity for secretion of IFN-γ and perforin, which are important for immune memory against TB infection. BTLA(high) αβ T cells also exhibited higher capacity in response to Mtb peptide stimulation. In contrast to the role of BTLA played for negative regulation of immune responses, our data in the current studies suggest that BTLA expression on αβ T cells is likely associated with protective immune memory against Mtb infection in the setting of patients with active pulmonary tuberculosis. This previous unappreciated role for BTLA may have implications for prevention and treatment of patients with Mtb infection.

Abstract
Transcriptomic research based on RNA sequencing (RNA-seq) technology is innovative and will provide new opportunities and biological perspectives for the use of ion-beam implantation in plants. Using RNA-seq, transcriptomes of whole rice seedlings generated from seeds implanted with a low-energy N+ beam were analyzed 96 h after planting. We identified 544 transcripts that were differentially expressed genes (DEGs) in the non-growth-inhibited sample implanted by an N+ beam, including 262 upregulated transcripts and 282 downregulated transcripts. Next, 776 transcripts were identified as DEGs in significantly damaged and growth-inhibited rice seedlings induced by N+ beam implantation, including 283 upregulated transcripts and 493 downregulated transcripts. The Gene Ontology (GO) analysis showed that 19 downregulated DEGs in the injured rice seedlings are enriched for the biological process GO term photosynthesis. The Kyoto Encyclopedia of Genes and Genomes pathway analysis also showed that 11 downregulated DEGs related to chlorophyll a/b-binding proteins are statistically significantly enriched in the photosynthesis-antenna protein pathway (Pathwayid: map00196). This result suggested that the downregulated and injured photosynthesis system contributed to the growth inhibition of rice seedlings induced by low-energy N+ beam implantation.

Abstract
Despite the recent realization of Interleukin (IL)-35 in tumorigenesis, its exact impact on colorectal cancer (CRC) progression and prognosis, however, is yet to be elucidated clearly. We thus in the present report conducted comparative analysis of IL-35 levels between CRC patients and matched control subjects. IL-35 is highly expressed in all CRC tissues, which can be detected in vast majority of colorectal cancer cells. IL-35 levels in CRC lysates and serum samples are highly correlated to the severity of malignancy and the clinical stage of tumor. Particularly, a significant reduction for serum IL-35 was noted in patients after surgical resection, indicating that IL-35 promotes CRC progression associated with poor prognosis. Mechanistic study demonstrated a significant correlation between serum IL-35 levels and the number of peripheral regulatory T (Treg) cells in CRC patients, suggesting that IL-35 implicates in CRC pathogenesis probably by inducing Treg cells, while cancer cell-derived IL-35 may also recruit Treg cells into the tumor microenvironment in favor of tumor growth. Together, our data support that IL-35 could be a valuable biomarker for assessing CRC progression and prognosis in clinical settings.

Abstract
PURPOSE To investigate the cervical spinal cord mapping on acupuncture at LI 4 (Hegu) and LI 11 (Quchi) by using 'Signal Enhancement by Extravascular water Protons' (SEEP)-fMRI, and to establish the response of using acupuncture in the cervical spinal cord. This research may provide some laboratory evidences from the acupuncture treatment on the cervical spinal cord of injuried patients. METHODS Seven healthy volunteers (healthy group) and three cervical spinal cord injury patients (injury group) were underwent low-frequency electrical stimulation at LI 4 and LI 11. Meanwhile, a single-shot fast spin-echo (SSFSE) sequence was used to perform functional MR imaging on a 1.5 T GE Signa MR system. The signals from the cervical spinal cord activated was measured both in sagittal and transverse imaging planes and then analyzed by AFNI (Analysis of Functional Neuroimages) system. RESULTS It was found that in the sagittal view, two groups had an fMRI response in the cervical spinal cord after given acupuncture treatments at LI 4 and LI 11. The localizations of the segmental fMRI activation were focused at C6 and C2 cervical spinal cord level. In the transverse imaging plane, significant fMRI responses could be measured from the four of seven healthy volunteers and from two of three cervical spinal cord injury patients. They were located at C6/7 segments. The cross-sectional localization of the activity measured in the spinal cord was most in terms of the ipsilateral posterior direction. The signal amplitude varied mainly between 6.8%17.8%. However, the difference found between the two groups had no statistical meaning. CONCLUSION The fMRI technique had detected an activation focused at C6 and C2 cervical spinal cord levels by use of acupuncture at LI 4 and LI 11 on a 1.5T GE clinical system. This proved that the meridians and points are found to be in existence. The fMRI can be used as a harmless research method to discuss the mechanisms of acupuncture as well as study the mechanisms of spinal cord diseases. It can be used to direct or monitor the related therapy on the spinal cord injury patients.

Abstract
The purpose is to investigate the cervical spinal cord mapping on electrical stimulation at LI4 (Hegu) by using 'signal enhancement by extravascular water protons' (SEEP)-fMRI, and to establish the response of acupoint-stimulation in spinal cord. Three healthy volunteers were underwent low-frequency electrical stimulation at LI4. Meanwhile, a single-shot fast spin-echo (SSFSE) sequence was used to perform functional MR imaging on a 1.5 T GE Signa MR system. Cord activation was measured both in the sagittal and transverse imaging planes and then analyzed by AFNI (analysis of functional neuroimages) system. In the sagittal view, two subjects had an fMRI response in the cervical spinal cord upon electrical stimulation at LI4. The localizations of the segmental fMRI activation are both at C6 through T1 and C2/3 cervical spinal cord level. In the transverse imaging plane, significant fMRI responses could be measured in the last subjects locating at C6/7 segment, the cross-sectional localization of the activity measured in the spinal cord was most in terms of the ipsilateral posterior direction. It is concluded that the fMRI technique can be used for detecting with activity in the human cervical spinal cord by a single-shot fast spin-echo sequence on a 1.5 T GE clinical system. Investigating the acupoint-stimulation response in the spinal cord using the spinal fMRI will be helpful for the further discussion on the mechanisms of acupuncture to spinal cord diseases.

Abstract
ARNT factors are a cluster of bHLH-PAS factors that heterodimerize with other specific bHLH-PAS factors to mediate a wide range of biological responses. Previously, we obtained a truncated form of ARNT2-like factor, ARNT2A, from zebrafish, which encompasses the basic-helix-loop-helix and PAS A/B domains, but lacks a transactivation domain at its carboxyl end. Herein, we report another truncated ARNT2-like factor, ARNT2X, in zebrafish, which differs from ARNT2A at its N-terminal region. In cultured ZLE cells, transiently expressed ARNT2X and ARNT2A inhibited 2,3,7,8-TCDD-activated cyp1a1 transcription with different efficiencies. In the developing embryo, arnt2X mRNA was consistently expressed in the retinal and neural tube regions until the hatching stages, but it exhibited a more specific pattern at larval stages, including expression in the brain, eyes, hypothalamus, pharyngeal skeleton, heart, liver, pronephros duct, pectoral fin, and epithelial cells of the swim bladder. In contrast, arnt2A transcription diminished after hatching. Microinjecting a recombinant arnt2X-expression vector into fertilized eggs before cleavage stages caused severe defects in brain, eyes, pectoral fin, heart, and gut development. This suggests that the ARNT-mediated signal transduction pathways play important roles in fish tissue development.

Abstract
The relative binding abilities of PY(3) (PMe(3), PMe(2)Ph, PMePh(2), PPh(3), P(OMe)(3), P(OMe)(2)Ph, PEt(3), P(OEt)(3), P(OEt)Ph(2), and dmpe) toward Re(V) were evaluated. The equilibrium constants for the reactions, MeRe(NAr)(2)[P(OMe)(3)](2) + PY(3) = MeRe(NAr)(2)(PY(3))(2) (1) + P(OMe)(3), decrease in the order PMe(3) > dmpe > PMe(2)Ph > P(OMe)(2)Ph approximately PEt(3) > P(OEt)(3) > PMePh(2) > P(OEt)Ph(2) > PPh(3). Both electronic and steric factors contribute to this trend. The equilibrium constant increases as the basicity of PY(3) increases when the steric demand is the same. However, steric effects play a major role in the coordination, and this is the reason that the affinity of PEt(3) toward Re(V) is less than that of PMe(2)Ph. A mixed-ligand complex, MeRe(NAr)(2)[P(OMe)(3)](PY(3)), was also observed in the course of the stepwise formation of 1. The large coupling constant, (2)J(PP) > or = 491 Hz, between the two phosphorus atoms suggests a trans geometry for the phosphines. Compound 1 catalyzes the oxidation of PY(3) by molecular oxygen. Kinetic studies suggest that the reaction of 1 with O(2) is first-order with respect to [O(2)] and inverse-first-order with respect to [PY(3)]. A mechanism involving a peroxorhenium intermediate MeRe(NAr)(2)(eta(2)-O(2)) is proposed for the catalytic processes. The reactivity of MeRe(NAr)(2)(eta(2)-O(2)) toward triaryl phosphines parallels that of the known compound MeReO(2)(eta(2)-O(2)).

Abstract
The tris(imido)methylrhenium complex CH3Re(NAd)3 (1a, Ad = 1-adamantyl) reacts with H2O to give CH3Re(NAd)2O (2a) and AdNH2. The resulting di(imido)oxo species can further react with another molecule of H2O to generate CH3Re(NAd)O2 (3a). The kinetics of these reactions have been studied by means of 1H NMR and UV-vis spectroscopies. The second-order rate constant for the reaction of 1a with H2O at 298 K in C6H6 is 3.3 L mol-1 s-1, which is much larger than the value 1 x 10(-4) L mol-1 s-1 obtained for the reaction between CH3Re(NAr)3 (1b, Ar = 2,6-diisopropylphenyl) and H2O in CH3CN at 313 K. Both 1a and 1b react with H2S to produce the rhenium(VII) sulfide, (CH3Re(NR)2)2(mu-S)2 (4a, R = Ad; 4b, R = Ar), with second-order rate constants of 17 and 1.6 x 10(-4) L mol-1 s-1 in C6H6 and CH3CN, respectively. Complex 4b has been structurally characterized. The crystal data are as follows: space group C2/c, a = 30.4831 (19) A, b = 10.9766 (7) A, c = 18.1645 (11) A, beta = 108.268(1) degrees, V = 5771.5 (6) A3, Z = 4. The reaction between CH3Re(NAr)2O (2b) and H2S also yields the dinuclear compound 4b. Unlike 1b, 1a reacts with aniline derivatives to give mixed imido rhenium complexes.

Abstract
Aryl hydrocarbon receptor nuclear translocator (ARNT) factors belong to a novel basic-helix-loop-helix-PAS (bHLH-PAS) transcription factor family that controls a variety of physiological and developmental processes. In a previous study, we obtained a partial complementary DNA fragment of an ARNT2-like factor from zebrafish embryo, liver, and other tissues by reverse transcription-polymerase chain reaction. In an effort to characterize the function of this factor, we screened an embryonic complementary DNA library and obtained a complete cDNA of this ARNT2-like factor, zARNT2A. The deduced protein sequence of zARNT2A encompasses the basic-helix-loop-helix and PAS-A/B motifs and shares highest sequence similarity with the amino-terminal half of mouse ARNT2 factor. However, it lacks a carboxy-terminal transactivation motif following the PAS-A/B motifs. Transient expression of zARNT2A in cultured cells resulted in repression of TCDD-dependent CYP1A transcription. Whole-mount in situ hybridization revealed that zARNT2A is expressed in brain and pronephros at prime-5 stages. In adult fish, zARNT2A messenger RNA is transcribed in a wide range of tissues, which indicates that zARNT2A and its corresponding signal transduction mechanisms have important roles in fish development and other physiological aspects.

Abstract
We investigated nitric oxide and cyclic GMP production in myocardium early after burn injury in rats. Nitric oxide synthase activity was measured in cytosol from the left ventricular wall of burned rats. Cytosol from control group animals was shown to contain mainly Ca2+-dependent nitric oxide synthase (cNOS) with a small amount of Ca2+-independent nitric oxide synthase (iNOS). Following burn injury, there was a marked increase in iNOS activity with a peak at 8 h post-burn, however, myocardial cNOS activity was found to decline. Parallel to iNOS induction there was a significant increase in myocardial nitric oxide and cyclic GMP production. All these changes were alleviated by treatment of the rats with dexamethasone. Since increases in cyclic GMP levels in the heart were associated with reduced myocardial contractility, it is possible that enhanced production of nitric oxide by a Ca2+-independent NO synthase accounts, at least in part, for the depression of myocardial contractility seen in burn animals and patients.

Abstract
Fusion of human red cells through the action of polyethylene glycol gives rise to pairs or higher clusters with a common membrane envelope, in which a barrier at the position of the original interface can be seen in phase contrast. At early times this septum contains lipids, as judged by labelling with a fluorescent lipophile, and transmembrane protein; this was shown by the presence of the preponderant component, band 3, detected by a fluorescent label, covalently attached before fusion at an extracellular site, or by immunofluorescence with anti-band 3 antibody. Ankyrin, which is bound to band 3, is also observed in the septum. The lipid thereafter disappears from the interface, carrying most of the band 3 with it. A continuous membrane skeletal network, defined by the presence of spectrin (detected by immunofluorescent staining in epifluorescence and confocal microscopy) appears to persist for long periods, but in many cells interruptions develop in the septum. In other fused pairs, particularly at longer times, the interface is seen to have vanished completely. Protease inhibitors have no discernible effect on any of these observations. The results suggest a model for the events that follow fusion. Covalent cross-linking of membrane proteins beyond a critical level causes inhibition of fusion, suggesting that proteins, probably the membrane skeletal network, regulate the fusion process. The efficiency of fusion is strikingly dependent on the composition of the isotonic medium, being relatively high at an orthophosphate concentration of 5 mM and minimal at 20 mM.

Abstract
Computed tomographic scans were done on 14 oral and maxillofacial malignant tumors in which pulmonary metastases occurred but were poorly delineated by conventional chest radiography and tomography. Computed tomography promotes the accurate diagnosis of small and occult pulmonary metastases. Optimal nonlinear computed tomographic windows are recommended for the diagnosis of pulmonary metastases.

Abstract
Because there are many similarities in infection and neoplasm of the infratemporal fossa (ITF), it is difficult to differentiate between these two diseases. By analysing 28 cases of the ITF lesions (8 cases of infection, 20 cases of neoplasm) the authors find the following points are important to differentiate between infection and neoplasm of the ITF. 1. The patients suffering from ITF infection almost all have odynophagia, while the patients suffering from the ITF neoplasm have no such symptom. The latter presents numbness in branches of the fifth nerve, while the former scarcely exhibits this symptom. 2. In the ITF neoplasm the mass could be found by CT or MRI, while in the ITF cellulitis no mass could be found. Although CT or MRI could find the mass in the ITF abscess, at the same time CT definitely could find some imaging signs which signify infection such as abscess formation (lucency) and gas bubbles. CT could find adjacent bone destruction in most ITF neoplasms, while this is rare in (ITF) infection. MRI is very helpful in differentiating between these two.

Abstract
Counseling coupled with a stages-of-change model in cigarette smoking cessation is a useful method for physicians to help patients stop smoking. The participants were 27 physicians, randomly assigned to three groups of nine physicians each. The first group of physicians were given two lectures on the stages-of-change model on which to base their patient counseling. The second group of physicians were not exposed to the model but a reminder reading "Ask your patients to stop smoking" was placed in their clinic. The third group of physicians were neither exposed to the model nor given any reminder. Of the 93 smokers among the patients of the 27 physicians, 39 were in the first group, 26 in the second, and 28 in the third. A survey indicated that among the three groups there was no significant difference in demographic data, cigarette smoking history, and personal attitude toward smoking cessation counseling. At the end of six months, the first group of patients accomplished a quit smoking rate of 28.6%; of the patients still smoking 56% had decreased their daily cigarette consumption. The corresponding figures for the second group were 8.3% and 9.1%. The corresponding figures for the third group were 4.3% and 13.6%. These data show that counseling coupled with the concept of a stages-of-change model is feasible and effective to assist with cigarette smoking cessation.

Abstract
The results of rapid percutaneous trough-needle biopsy of lung lesions in 68 cases (76 punctures) is reported. It was successful in 60 of the 68 cases (89.1%). After localizing the lesion on the simulator, TV screen of X-ray machine, or chest film, the procedure was performed with the X-ray switched off. Pneumothorax was observed in 8 cases (8/76 punctures, 10.5%) by routine chest film taken 1 1/2-2 hours after biopsy. 4 patients were asymptomatic (atelectasis below 20%). Pneumothorax could be induced if the needle was at an acute angle with the surface of the pleura at the time of puncture. The needle should pierce the pleura perpendicularly. Premature removal of the pith with the slot tip half-through the pleura might have been another cause of pneumothorax. As the movement of a coin lesion is wide during respiration, the patient must be trained to hold his breath at the end of inspiration or expiration and remains so during the puncture. The chance of success in puncturing a coin lesion could be increased if the lesion is so immobilized and visualized as it is pin-pointed with the rib out of the way at the time of puncture.

Abstract
To investigate the synergism or cooperative interaction between transcription elements, we have designed and constructed a series of synthetic polymerase II promoters with different combinations of elements. These include three different CCAAT boxes, which correspond to the binding sites for CP1, CP2, and NFI, a GC box, a CACCC box, and an ATF/CREB-binding site. The synthetic promoters containing these elements in proximal positions were linked to a test gene (CAT). Tandem repeats of AP1- and AP2-binding sites, the simian virus 40 enhancer, and DNA-binding sites for GAL-estrogen receptor were cloned downstream of the test gene. The strength of these promoters was then tested in transient-expression assays in HeLa TK- cells. In the context of the adenovirus major late promoter TATA box, the promoters containing only certain combinations of elements are active in this assay. Some elements appear to cooperate nearly universally, but others exhibit strong selectivity. These results indicate strongly selective synergistic interactions between elements and suggest that levels of promoter strength may be determined by the extent of compatibility between factors bound to proximal and enhancer sites.

Abstract
By means of X-ray photography tests were made of 224 (100 males and 124 females) volunteer Chinese adults of Han nationality to study the related regular patterns of superimposed projection of face landmarks onto the skull. On the basis of these tests, the present article reveals from a forensic anthropology angle the related regular patterns of plane projection of the human face with its skull. Study shows that there exist a strict individual identity and exclusiveness in relation between the human face and skull. The related regularity of displacement of face landmarks appears in projection of the skull with the human head at different photographic positions and angles. On the basis of this discovery, 52 indexes in 4 groups were established as a standard for judging the identification of a skull's body origin by means of skull-image superimposition. Based on forensic anthropology, the technique has raised to a great extent the credibility of unknown skull identification. In the past 8 years, 89 unknown skulls have been identified with their body origins which provided important and accurate evidence for the solution of murders with dismembered bodies, skeletonized bodies, and unidentified dead bodies.

Abstract
This study suggests that damage to the intestinal lining, an important mechanical barrier against bacterial invasion, is the main factor leading to the dissemination of endogenous microbes. Reduced phagocytic activity of Kupffer cells and compromised opsonic function also appear to contribute to the process.
